Klebanoff began his real estate career as a mortgage broker and multi-family property owner with his own firm. Over 25 years ago, he joined Dorman & Wilson as a mortgage banker, which was subsequently purchased by Legg Mason Inc. before being rolled into Legg Mason Real Estate Services. In September 2003, LMRES sold its interest to NorthMarq Capital Inc. By that time, Klebanoff was managing director of the New Jersey office of NorthMarq. He was directly responsible for the June 2004 acquisition of James R. Poole & Co. Inc. In 2007, NorthMarq honored Klebanoff with the company's most prestigious award of achievement: the Michael O'Brien President's Award.

In addition to his post as senior vice president and co-managing director of the New Jersey office, Klebanoff was also a member of the executive management committee of NorthMarq Capital. He helped expand the New Jersey staff and raised production eightfold to around $1 billion per year. During his career, Klebanoff arranged more than $5 billion in commercial real estate financings.

"Marty was an extremely gifted mortgage banker who always thrived on the more challenging structured finance assignments," says Gregory H. Nalbandian, senior vice president and managing director at NorthMarq Capital. "He was the consummate dealmaker, a wonderful mentor and a very giving individual to the profession and, more importantly, to his family."
